Scope

This project will develop and deploy the GEMINI instrumentation and measurement framework, capable of supporting the needs of both GENI experimenters and GENI infrastructure operators. It uses the perfSONAR system as its basis, and will include capabilities being developed by key GENI I&M projects, including LAMP and INSTOOLS. It will collect and manage both substrate metrics as well as slice-specific measurements. It will introduce a GENI Global I&M Registry so that GEMINI components can locate one another, and locate measurement sources and data. It will include access control for instrumentation infrastructure, measurements, and measurement data based on GENI policy and authorization mechanisms.

Strategy and Goals

The GENI LAMP project has adapted perfSONAR code for operation in a protoGENI slice, and has included the Periscope display module. The GENI INSTOOLS project has written easy-to-use tools for experimenters who wish to instrument their protoGENI slice.
This GEMINI project will merge LAMP (including perfSONAR and Periscope) code and features, with INSTOOLS code and features, to form one set of GEMINI I&M services that can be flexibly deployed in a defined range of GENI environments.

Its first goal is to provide easy-to-use I&M services for experimenters, who are deploying slices in GENI on selected types of servers, VMs and racks, interconnected by various types of network paths.
Its second goal is to provide comprehensive infrastructure measurement services for infrastructure operators, who are deploying measurement slices on selected types of servers, VMs and racks, interconnected by a various types of network paths. In addition, slices established by other infrastructure operators, or by experimenters, can be authorized to gather data from the measurement slices, via interfaces that retain compatibility with currently deployed perfSONAR services.

This project will build and operate three persistent services, including a GENI Global I&M Registry (i.e., UNIS), a GENI Experimenter Portal Service and a GENI Event Messaging Service; these can be utilized by all types of GENI I&M services, including those developed in the GIMI project. The GENI Experimenter Portal Service will be developed in cooperation with the GIMI project, to support both GEMINI and GIMI tools. This project will utilize a persistent service provided by the GIMI project, the GENI Measurement Data Archive service (i.e., iRODs). It will use the GENI Measurement Data Object Descriptor (MDOD) schema, defined for use by all GENI I&M services.
